6.8 Connecting the base plate pneumatics
Depending on the application, the base plate is a single subbase or base plate for
stacking assembly.
1 2
Fig. 8: Connecting the base plate pneumatics
1. Connect the supply line to inlet connection°1 on the base plate (1).
2. Connect the outlet line to the output connection (unlabeled connection) on
the opposite side.
3. Always connect a silencer or a line for restricted exhaust at exhaust air connec-
tion 3 (2). The exhaust must not be sealed by a screw.
4. With a pressure range of -1 bar ... +1 bar, connect vacuum to exhaust 3.
CAUTION! Never undo the blanking screw during operation.
Device is operating under pressure. If the alternative inlet connection (3) on
the base plate is opened, the blanking screw may be forced out by the escap-
ing compressed air.
7 Commissioning
7.1 Preparation
General requirements
1. Implement safety measures. See
7.2 Step-by-step commissioning
Follow the steps below to carry out commissioning.
• Step 1: Switch on the 24 V electronics supply voltage.
• Step 2: Establish communication with PROFINET.
• Step 3: Switch on the pneumatic supply.
• Step 4: Switch on the 24 V actuator supply voltage.
• Step 5: Stipulate the set point via PROFINET using the control.
INFO: Select the correct supply pressure. (The supply pressure should always be
higher than the output pressure.)

General requirements
• Never switch off, modify or bypass safety devices.

measures.
• Do not touch the product or any connected parts during operation.
In case of malfunctions during operation
• In case of a malfunction that presents an immediate danger for employees or
L
systems: Switch off product.
• Carry out analysis and troubleshooting of malfunctions. See
bleshooting.
8.2 Controlling the product
Once the electrical supply and pneumatic supply have been connected on the
product, the pressure or the measurement can be continuously adjusted at the
process input.
A control specifies the set point on the control valve via the Ethernet-based
PROFINET fieldbus.
The measured pressure and the measurement at the process input are sent cycli-
cally to the control via PROFINET.
)
A
The regulator (controller) compares the set point with the output pressure mea-
sured with a pressure sensor.
The control variable is used to control the proportional solenoids and thus the air
supply or exhaust valve to adjust the required pressure.
With cascade control, the regulator (controller) compares the set point with the
measurement at the process input and sets the specified process value using the
proportional solenoids.

8.3 Pressure control
"Closed loop" pressure regulation – parameter sets
The implemented regulation structure enables the use of various types of regula-
tors.
Valve behaviour for set point equal to zero [PCS_CMD0]
When the valves receive a set point of 0 mbar, the valves exhaust as quickly as
possible until the minimum pressure (default: 50 mbar) is reached.
If the actual pressure is less than the minimum pressure value, the exhaust valve
remains open or closed. See
Safeguards to retain function
If a stationary control deviation is detected over a longer period of time, the coil
current is reduced to prevent excessive heating.
9 Service
9.1 Inspection
9.1.1 General requirements
Use in normal ambient conditions
• Inspection interval: The product must be checked monthly for contamination
and damage.
Use in aggressive ambient conditions
Aggressive ambient conditions include, for example:
• Minimum or maximum permissible temperature. See
